write short note sericulture
Answers
Answer:
Sericulture is the process of cultivating silkworms and extracting silk from them.
Explanation:
The production of silk generally involves two processes:
- Care of the silkworm from the egg stage through completion of the cocoon.
- Production of mulberry trees that provide leaves upon which the worms feed.
The silkworm caterpillar builds its cocoon by producing and surrounding itself with a long, continuous fibre, or filament. Liquid secretions from two large glands within the insect emerge from the spinneret, a single exit tube in the head, hardening upon exposure to air and forming twin filaments composed of fibroin, a protein material. A second pair of glands secretes sericin, a gummy substance that cements the two filaments together. Because an emerging moth would break the cocoon filament, the larva is killed in the cocoon by steam or hot air at the chrysalis stage and silk fibre is made from this cocoon filament.
Answer:
Sericulture, also called silk farming, is the process of making silk fibers. It starts by raising silkworms and then processing the fibers they produce. ... The thread can then be twisted into silk yarn or woven into silk cloth (fabric).
